Types

type ConjunctionQueryScorer

type ConjunctionQueryScorer struct {
	// contains filtered or unexported fields
}

func NewConjunctionQueryScorer

func NewConjunctionQueryScorer(options search.SearcherOptions) *ConjunctionQueryScorer

func (*ConjunctionQueryScorer) Score

func (s *ConjunctionQueryScorer) Score(ctx *search.SearchContext, constituents []*search.DocumentMatch) *search.DocumentMatch

func (*ConjunctionQueryScorer) Size

func (s *ConjunctionQueryScorer) Size() int

type ConstantScorer

type ConstantScorer struct {
	// contains filtered or unexported fields
}

func NewConstantScorer

func NewConstantScorer(constant float64, boost float64, options search.SearcherOptions) *ConstantScorer

func (*ConstantScorer) Score

func (s *ConstantScorer) Score(ctx *search.SearchContext, id index.IndexInternalID) *search.DocumentMatch

func (*ConstantScorer) SetQueryNorm

func (s *ConstantScorer) SetQueryNorm(qnorm float64)

func (*ConstantScorer) Size

func (s *ConstantScorer) Size() int

func (*ConstantScorer) Weight

func (s *ConstantScorer) Weight() float64

type DisjunctionQueryScorer

type DisjunctionQueryScorer struct {
	// contains filtered or unexported fields
}

func NewDisjunctionQueryScorer

func NewDisjunctionQueryScorer(options search.SearcherOptions) *DisjunctionQueryScorer

func (*DisjunctionQueryScorer) Score

func (s *DisjunctionQueryScorer) Score(ctx *search.SearchContext, constituents []*search.DocumentMatch, countMatch, countTotal int) *search.DocumentMatch

func (*DisjunctionQueryScorer) ScoreAndExplBreakdown

func (s *DisjunctionQueryScorer) ScoreAndExplBreakdown(ctx *search.SearchContext, constituents []*search.DocumentMatch,
	matchingIdxs []int, originalPositions []int, countTotal int) *search.DocumentMatch

This method is used only when disjunction searcher is used over multiple KNN searchers, where only the score breakdown and the optional explanation breakdown is required. The final score and explanation is set when we finalize the KNN hits.

func (*DisjunctionQueryScorer) Size

func (s *DisjunctionQueryScorer) Size() int

type TermQueryScorer

type TermQueryScorer struct {
	// contains filtered or unexported fields
}

func NewTermQueryScorer

func NewTermQueryScorer(queryTerm []byte, queryField string, queryBoost float64, docTotal, docTerm uint64, options search.SearcherOptions) *TermQueryScorer

func (*TermQueryScorer) Score

func (s *TermQueryScorer) Score(ctx *search.SearchContext, termMatch *index.TermFieldDoc) *search.DocumentMatch

func (*TermQueryScorer) SetQueryNorm

func (s *TermQueryScorer) SetQueryNorm(qnorm float64)

func (*TermQueryScorer) Size

func (s *TermQueryScorer) Size() int

func (*TermQueryScorer) Weight

func (s *TermQueryScorer) Weight() float64
